Short answer. Generally yes. Article 2154 of the Civil Code sets out solutio indebiti: if something is received when there was no right to demand it, and it was delivered by mistake, the person who received it has an obligation to return it to you.
What the law says
If something is received when there is no right to demand it, and it was unduly delivered through mistake, the obligation to return it arises.

Two conditions have to both be true
Article 2154 sets two requirements together, not one on its own. First, the recipient had no right to demand what was received — there was no valid claim entitling them to it. Second, it was unduly delivered through mistake — the payment happened because of an error, not as a deliberate gift or a payment made knowingly despite doubts about whether it was owed. Both elements need to be present for this article's obligation to arise.
The obligation is on the recipient, and it is automatic
Once those two conditions are met, the article states the consequence directly: the obligation to return it arises. This is not something that depends on the recipient agreeing they were mistaken, or on you having to persuade them — the law itself creates the duty to return once a mistaken, undue payment has occurred. The recipient holding onto money or property they had no right to receive, delivered because of your error, is legally obligated to give it back.
Why the word 'mistake' does real work here
This article is built specifically around error. If you paid someone knowing full well there might be no obligation to pay — for instance, out of generosity, or to settle a disputed claim you chose not to contest — that is a different situation from an honest mistake, such as paying the wrong account, double-paying, or paying an amount you did not actually owe. Establishing that the payment really was a mistake, rather than a considered choice, is central to relying on this article.
What to do if this has happened to you
Document the payment itself — the amount, the date, and what led you to believe it was owed — along with whatever shows the payment was actually unwarranted. That record supports a demand for return under Article 2154 if the recipient does not return the money voluntarily once you point out the error. A lawyer can help you formalize that demand and pursue recovery if the other side does not cooperate.
